Brewer's largely unfettered path to the GOP nomination was unexpected as recently as this spring. The governor, who spent a contentious first year in office after then-Gov. Janet Napolitano took a Cabinet position in the Obama administration, became embroiled in budget battles with members of her own party and was considered very beatable heading into this year's election cycle.

But voters' passage of a 1-cent-per-dollar increase in the state sales tax, a measure Brewer championed for nearly 18 months, coupled with her signing of Senate Bill 1070, the state's tough new immigration law, changed the scope of the primary election.

Most of her competition - former Arizona Board of Regents President John Munger, state Treasurer Dean Martin and Paulden businessman Buz Mills - suspended their campaigns or withdrew from the race, leaving Jette as the only active candidate.

Martin and Mills' names both appeared on the ballot, though votes cast for Martin were not counted.

Brewer and Goddard are not the only names that will appear on the November ballot. Glendale currency trader Barry Hess had a sizable lead in the Libertarian primary; the Green Party's Larry Gist ran unopposed.

The public will have its first opportunity to hear from the candidates next Wednesday, when Brewer and Goddard square off in a televised debate required for candidates running with public funding.

Goddard also has challenged Brewer to six debates around the state but her campaign has not responded as yet.
